Turntable Bearing Products - Easy Mount with Bolt Holes

Need to make a scanning system that requires precise rotary movement?  Our "Thin Section" turntable bearings are an excellent way to begin your project.  Below is an example of a product that can do this.  It is easy to mount via either thru-holes or tapped threaded holes. Both options are available with one bearing.

Turntable Bearing

With Mounting Holes

Thin Section Low Profile

Inner and Outer ring holes for easy mounting.  No need to precision machine large ring holes for mounting inner or outer ring.

You will only need to drill the appropriate matching bolt hole pattern (at the specified pitch circle diameter) for each ring in your structure.

To design an indexing system we will need several bits of data such as the payload weight, speed (min and max rpm), duty cycle, along with accuracy and repeatability requirement prior to estimating the cost of the system.

We use SolidWorks as our primary design tool and can typically import any sketch or 3D model that you wish to share.

Compact Low Profile Precision Turntable Bearing

These bearings have special features that make them easy and quick to install into your application.

Rings Offset

Inner and Outer slightly
offset to allow clearance for
free rotation when mounted.

Outer Ring holes

Thru-holes w/ counterbore

Inner Ring holes (opposing side)

Thru-holes w/ counterbore


Bearing quality hardened steel for all standard catalog products. Stainless steel is available for lot orders of 20 pieces or more.
